1 MEASURING INSTRUMENTS - STRUMENTI PER MISURARE CORROSION DATA GUIDE

3 CORROSION DATA GUIDE This guide was developed from general corrosion literature, standard references and field experiences. Recommendations for corrosive service are given to assist the user in making the appropriate material choices for an application. This table must be regarded as indicative only and not as any guarantee for a specific service. Any material will behave differently under the influence of such variables as pressure, temperature, flow rate, mixtures, concentrations and aeration of fluids, etc. For that reason the end user is responsible to choice of appropriate material in his own application. Nuova Fima S.p.A. cannot garantee that a material is suited to a particular application and cannot accept responsability for any problems caused from use of this data guide. Nuova Fima S.p.A. remember moreover, that careless use of this document could be dangerous for people life and properties. LEGEND A = Recommended Best service life Attack < 0,05 mm/year B = Suitable Good service life Attack 0,05 0,5 mm/year C = Not recommended Fair service life Attack 0,5 1,27 mm/year D = Unsuitable No service life Attack > 1,27 mm/year (*) The symbol in this column indicated that Fluorolube is a liquid fill for gauges and diaphragm seals required for use with oxidizing substances Pag. 1

Naming Compounds. There are three steps involved in naming ionic compounds- naming the cation, naming the anion, and naming the entire compound.
Naming Compounds Naming compounds is an important part of chemistry. Most compounds fall in to one of three categories ionic compounds, molecular compounds, or acids. Part One: Naming Ionic Compounds Identifying
